Domestic sewage contains increasingly more pharmaceuticals and personal care products (PPCPs), due to rising use of medicines, health supplement food and daily necessities. And various types of industrial wastewater from pollution sources in treatment areas could flow into the public sewerage treatment plants (PSTPs) in metropolitan areas. The conventional PSTPs are designed to treat suspended solids, biodegradable organics, nitrogen and phosphorous from residential and industrial areas and public facilities. However, toxic, conventional, and non-coventional pollutants from non-domestic sources that discharge into sewer system as well as domestic source with various chemicals could not be treated in the conventional PSTPs and discharged untreated to public basin. In this paper we aim to consider the establishment system of effluent standard of PSTPs in comparison with water quality standard of water environment and wastewater discharge regulation. And also we suggest the necessity of regulations on the pretreatment of industrial wastewater as part of efforts to improve water quality in sewerage systems and to protect public basin.

Our study researched on unification of KS I ISO standard harmonized with ISO and Official Test Method enacted by Korean Ministry of Environment-drinking water and indoor air quality. We reviewed KS methods related to drinking water and indoor air quality for about 23,000 KS methods. KS methods related environmental field are classified as KS I, total 635 methods and 583 KS I methods were harmonized with ISO. For Environmental Standard methods for drinking water, 100 methods were reviewed according to 232 KS methods related to ISO/ TC 147 "Water Quality". Environmental Standard methods for indoor air quality were reviewed according to 95 KS standard methods related to ISO/TC 146 "Air Quality". By reviews and comparison tests for unifiable ES for drinking water and indoor air quality with KS methods harmonized with ISO, it was evaluated that for 100 ES methods for drinking water, 23 ES methods were unification complete, 29 ES methods were unification possible, 12 ES methods were unification impossible, no corresponding methods were found in KS I ISO for 36 ES methods and for 17 ES methods for indoor air quality,1 ES methods were unification complete, 3 ES methods were unification possible, 3 ES methods were impossible, no corresponding methods were found in KS I ISO for 10 ES methods.

Standard weather data available to greenhouse environmental design are limited in most regions of the country. So, instead of using standard weather data, in order to find the method to build design weather data for greenhouse heating and cooling, design outdoor weather conditions were analyzed and compared by TAC method and frequency analysis using climatological normal and thirty years from 1981 to 2010 hourly weather data provided by KMA and standard weather data provided by KSES. Average TAC values of outdoor temperature, relative humidity and insolation using thirty years hourly weather data showed a good agreement with them using standard weather data. Therefore, in regions which are not available standard weather data, we suggest that design outdoor weather conditions should be analyzed using thirty years hourly weather data. Average of TAC values derived from every year hourly weather data during the whole period can be established as environmental design standards, and also minimum and maximum of them can be used as reference data.

The road traffic noise has emerged major noise as the overcrowding of the urban population and the explosion of car storage capacity. There are limits for establishing the measures to meet noise standard because of the increase of high-rise building and insufficient distance between residential areas and road in urban center areas. Therefore, this study analyze the problem of the application of national road noise standard, and present the alternatives to achieve environmental standards in conjunction with the soundproofing measures. To reduce the population ratio exposed to road noise on seoul motorway, we suggest some action plane are as follows: i) Roadside noise standard of nighttime beside daytime is the first noise reduction goals ii) Noise standard of Noise and vibration control act is priority in case of existing area iii) Noise standard of basic environmental policy act is priority in case of new area.

The variation of stream flow is the one of the most important factors which influence on that of water quality in the unit watershed. The target water quality goal is established and permissible load is allotted in the base of the standard flow condition along with its water quality for the management of Total Maximum Daily Loads (TMDLs). A standard flow selected could cause problems in the load allotment if it was not properly arranged. This study reviewed the acquisition of water quality data, the self-variation and the retainability in water quality on the specific flow conditions. This study also proposed the median and the adjusted average flow condition out of general flow conditions as alternative standard flow conditions. It is considered that the alternatives can make the water quality data easily acquired and the water quality representativeness more enhanced on the standard flow conditions.

The Environmental Site Assessment System(ESAS) in Korea which became effective as of 2002 is very similar to the ASTM standard practice in United States. Unlike the United States, however, we do not have Phase I ESA, enough environmental professionals with approved training and practical experiences, and detailed guidelines for a governmental action. As a result of comparison the ESAS with the ASTM standard practice, the ASTM standard practice is focused on the Innocent Landowner Defense and has a difference in data search process as well as legal and methodological ways from the ESAS. Therefore, the Transaction Screen Process in ASTM E-1528 standard practice is suggested to reduce the risk potentially produced under on-site assessment and to achieve efficient on-site assessment. In addition, social and executive supports are discussed to more activate on-site assessment. In near future this study is expected to be standardized more in detail with activation of on-site assessment and it is also expected to increase the role and responsibility of environmental professionals considerably.

Inductively coupled plasma atomic emission spectrophotometer (ICP/AES) is a versatile modern instruments for the multi-element analysis, but quantitative analysis using ICP/AES with normal pneumatic nebulizer is not applicable for the measurement of elemental concentrations in water down to the drinkining water standard level except a few elements because of poor detection limits. However, the detection limit can be lowered enough to measure drinking water standard, if ultrasonic nebulizer and/or hydride vapor generator is attached. This method is tested with groundwater samples from Tajeon area. It is confirmed that the elemental concentrations in these samples are within the limit of drinking water standard for the most elements. However, uranium concentration is very high in some samples compared with the concentrations suggested by Environmental Protection Agency of U.S.A. There is no standard concentration level to this element in Korea and it should be prepared immediately.

The primary purpose of this research was to set up the standard guidelines for the planning of interior architectural environments of the detention facilities at the Korean Police Stations. By visit-studying the actual interior environmental conditions of 5 different kinds' domestic Correcting Facilities and 5 domestic police detention facilities and 2 foreign police detention facilities, comparing them to the existing Korean correctional institutions' cell facilities, that the strengths and weaknesses had been analyzed to extract the main concepts and the planning scheme for the Standard Korean Police Detention Facilities. By reserching the National human Right Commitee's Anual Reports, three different indexes were picked out for those analysis : the Environmental control index, the Detention Service support index, the Environmental support index. These three indexes will be used as Key factors for the planning of interior architectural environments of the detention facilities at the Korean Police Stations.: (1)the Environmental control index to establish the Space Program, the Spatial Hierarchy and the horizontal & vertical Security Blocks, (2)the Detention Service support index for the central Environmental Control & Security System, the Secured Privacy for both detainees & police offices, (3)the Environmental support index for the gender-respected segregation of cell zones, the psychological & physical safety design factors, the construction standards of all rooms in a detention facility. The result of this study should be used as the guidelines for "The Standard Plans and Regulations for the Korean Police Detention Facilities" to respect fundamental human rights.
